'ork, have: invented a certain new and useful vImprovement in Signaling Systems, of which thefollowing is a full, clear. concise.; and exact description, reference being had tothe accompanying drawings, form- 10, in g apart of this specification.

My invention relates to combined telephone and telegraph systems, particularly to-'systems used in municipalities where the saine line is used `for transmitting fire alarm signals and4 for transmitting telephone and tclegraphic signals and messages, that is, a line which may be used in common by the fire de. )art-ment and the police department.'

n my Patent- YNo. 807,235, dated Decen1 lier 1 2, 1905, I describe a system ada ted to suclruse, but in this patent the chie object of vmy invention is to prox-'idc locking-out means whereby when one substation is in use for` tclegraphic or telephonie purposes an- 25. other station is prevented from using the line orinterfering withv the conversa tion or signals from the4 rst station, and to provide means whereby the line is at all times in perfect c0ndition to transmit fire alarm signals independently ofthe telegraph or telephonie apparatus and circuits.

.My inventiony can be best understood by reference to the .accom anying drawin in which l diagranimatica ly illustrate a ine connecting at! one end with the central station signal receiving apparatus and at the outside connecting with tire alarm substations and with telegraphic and telephonie substations,

The main line consisting of the line limbs 4G a. and b is normally closed through a central i battery or other source of current 1. At the central Station a nonsensitiverclay 2 and a sensitive relay 3 are included serially in the line, and the primary winding -l of an induction. coil is also serially included in the line, the secondary Winding 5 of the induction coil being connected to the sleeve and tip strand springs 6 and 7 of the telephonie spring jack 8 at the centra lexchange.

of the key 11 connects the operators telephone apparatus 14 with the answerin plug,

-and actuating spring 15 is mechanica y connected with the sleeve spring 6 which spring 15 normally, engages the contact s ring 16, 50 and upon insertion of the plug within the jackengages the alternate contact spring 17. The actuating spring 15 is connected with the line at the central station side of the repeating or induction coil, While the contact s ring 16 engages the line at the oth er side of t e induction coil, the primary winding of the induction coil-being thus short-circuitedwhen the plug is removed from the ack. The alternate spring 17 is connecte with the line 'm so that upon insertion of the plug in the jack the relays 2 and 3 will be short-circuited as the actuatingspring 15 engages the alternate spring 17, the primary winding being then included in circuit u on disengagement of the Y actuating-spring tgi'orn the normal cont-act; spring 16.

At each ofthe ire alarm stations F, of which there may be any number, is a normally closed circuit breaker 18 having mego. chanical connection with the code wheel 19 in such a ma'nner that upon rotation of the code wheel in a manner Well known in telephonie art the`circuit breaker will be repeatedly opened, thereby to repeatedly open the 35 line c--b. i

At each telegraphic Vand telephonie. station, of which there may be any number, there is provided a controlling solenoid switch 20. This solenoid switch consists of 9o the core 21 suspended at its ends from the ivothangers 222A and 23. The greater of ront part 24 of the core is. of magnet-ic niaterial, preferably stranded iron, wiile the rear part-25 is of non-magnetic material such as 95 aluminum or brass. The magnetic frame 26 of the awitch surrounds and protects the Winding 27, the greater art of which winding encircles the magnetic part of the core so that upon proper current flow the core will be attracted. The front end of the core is provided with a cap or abutment 28for en` gaging the 'frame 26 after the core has been attracted its full distance. Extending from the hanger 23 is a contact arm .29 engaging 105 the contact' .30 being preferably a mercury cup so that -the contact between the mercury and the. arm :29 will not be broken until the cap 225 of the core has been brought into engagement with' the magnetic frame 26. no

53o oid windin 5S '-ltnally including the tip spri The apparatus at the' telephone and telegaph stations may be inelosed in a box, in which are rovided the contacts 31 and 32 which are in engagement when thebox is 5 closed but which are carried out of engagement when the box is o ened. The box is also rovided'with a loc 33 to the rear of whic at the interior of the box is provided s ring .jack mechanism 34 consisting of the Aed forA engage'mentwith t e sleeve and tip contacts 37 and 38, respectively, of the key 391 This kev is of the construction shownand is provided with the code wheel 40 and the circuit breaking switch 41 connected with the tip and sleeve members 37 and 38, the

hey being also provided with spring actuat' mg mechanism not shown, whereby the code wheel 40 is revolved after the key has been inserted through the lock and into engagement with the springjack 34, insertion of the key also causing disengagement of the contacts 42 and 43' associated with the springck. Normally the mainline is continuous 25 rough each substation along a circuit seriall including the contacts 31 and 32 and tlielack contacts 42 and 43, the line connect- 'ing `with this circuit at the main binding posts 44 and 45. One terminal of the solen- 27 connects with the binding 90st 44 an the other terminal thereof connects with the contact arm 29, the contact #being connected with the binding post 45. q One terminal of a winding 46 having a high 35 impedance with a'comparatively low resistance connects with the arm 29 'and the other terminal thereof connects with the contact 30, this Winding being thus normally shorttcil'cuited. Telephonie apparatus consisting .40 of the receiver 47 and the transmitter 48 are serially connected in circuit with the contact arm 29 and contact 30 in bridge of the wind, ,ing 46. The normally open switch 49 is con- 'nected in bridge of both the winding 46 and 45. the teiephonic apparatus and is associated with the code whee 50 whichupon actuation will cause repeated closure of the switch 49 landA thus short-circuiting of the winding 46 and tele honic apparatus.. A switch hook 50 A51 for herding the receiver is associated with ai?` tacts 31, 32, 42 and 43, all apparatus within the box being thus short-circuited. Upon bpening of the box, however, this short path is opened, and the winding 27 of the solenoidliitch 20 will then primaril be the only B5 patates in circuit, the win ing 46 ve spring' 35 and the ti spring 36 adaptman phonic ap aratus short-circuited through t e arm 29 and contact 30. s will be described later Ythe solenoid,-how ever, becomesenergize to o between the arm 29 d `t e contact 3() livers 'this current when the solenoid 27 at a substation is in circuit, these solenoids havinga very low resistance. The relay .2 in-v cluded seriallyin the main line is adjusted to become denergized only upon an absolute break in the line, while the relay 3 is more sensitive and will release when the'current flow falls below say 90 millieamperes. The armature 54 is normally attracted by the relay 2 away from its contact 55, and the armature 56 of the relay 3 is nonmally attracted away from its contact 57. One terminal of the battery 58 connects with the contacts 55 and 57, while the lother terminal of the battery connects with one terminal of a registering device 59 whose other terminal connects through the conductor 60 and conductor 61 with the armature 54, the conductor 61,in cluding the electromagnet 62 also associated with the armature 56. A lamp 63 or other indicating-signal connects with the armature 56 and with-the conductor 60. The operation of the system now becomes apparent. Starting with all the substation apparatus in its normalcondition, suppose an alarm of fire is to be sent to the central 'station'. The codeapparatus Fat the proper iire alarm station is set in operation to re' peatedly o en the switch 18, whereupon current flow t ough the main line is repeatedly interrupted. Each interruption of the current causes release of the relays 2 and 3. The

armature 54 of the relay 2 engages its contact 55 and a circuit is closed from the bat tery 58 through the register mechanism-59,

through the conductor v60, throu h conduci tor 61, through the winding of t e electromagnet 62 to the armature54 and ,from`the .contact 55 back to the battery. Denergi'zation of the` relay 3' hasa tendency to release the armature56, but this is prevented by the electromagnet' 62 included in the circuit just traced. The lamp 63, therefore, is prevented from being included` in 'circuit' and' consequently is not affected, and where the cen-v tral operator receives signals on the register device 59 only, she knows that the'v'jsignal emanates from the fire alarm box: p

If it is desired to have telephomc conversation with the centralexchangc, for instance, a police officer' desiringto; report to* the' PNP( at the central exchange', the

n the circuit v whereupon the winding 46 and the tephomc apparatus at one ofthe substations T is utilized. The officer inserts his key into the lock and into the. springjack thereby breaking connection between'the contacts 42 and 43 whereby the short circuit path through the substation broken and the solenoid 27 included in circuit, as before described, The

dimensions of the winding 27 and the adjustment of the core and pivoting supports therefor are such that the core will bestarted only when the current flow is at or very *close to `the maximum current flow, in this case .130

milli-amperes.' This current primarily Hows through the winding upon breaking of the short circuit path, and the core is immediately pulled inwardly to bring the cap 28 into engagement `'.fith the magnetic frame '26.

Upon consequent disengagement of the' arm 29'from the contact 3() the impedance wind-` ing 46 and telephonie apparatus will be included serially in circuit and in series with the solenoid 27, as before described, this inclusion in circuit of the winding 46 and telephonic apparatus being practically simultaneous with the insertion of the keyin the lock. Upon insertion of the key in the springjack also the contact is broken between the tip springr 36 and the normal contact s ring, and the switch 41 is connected 30 with t e tip and sleeve contacts ofthe springjack. The circuit which -now cserially includes the'switch 52 held closed by the receiver hook and the switch 41- after insertion of the key short-circuits the telephonie apparatus and the winding 46, that is, only the low resistance of the solenoid 27 is inircuit. Upon turning of' the key, however, to open the lock the code wheel 40 will be actuated to cause repeated opening of the switch 41 and 40 lot' this short circuit, whereby the parallel resistanc'e 'ofthe winding 46 and the telephonie apparatus will be alternately included in the line which will reduce the current flow there-- through to 9() milii-amperes and thus the 4 51ciirrent low in the line will alternate from the maximum value or 130 milli-amperes' to the minimum value or 90 willi-empates, this continuing until the roper code signals have bee'n sent from the. ey, these signals corre- 'spondine to the number of the particular key vusedj- This variation in current from 130 to vv milliamperesaiiects onlyvthe relay 3, the relay 2, as before described, being responsive only to absolute breaks in the line. Upon Teach reduction in current, therefore, the re- 7* i 'lay 3 will release'its armature 56 which, upon.

'engagement with its contact 57, closes the following circuit: from the battery 58 through the register device 59, conductor 60, 30 lam 63, armature 56, and from contact 57 bac to the battery, both the registering device and the lamp responding, the registering device causing a record to be made.

As before stated, it reqiuir the full maximum current flow to cause a solenoid core tobe started, and. therefore, even though the box at another substation be, opened, the solenoid core thereatwill not respond and the contacts 29 and 30 at this other substation will not be disconnected but will maintain the short circuit about the telephonie and telegraphic apparatus, and signalin from the second box will be entirely locke out. The oicer at the second station then upon` removing the receiver immediatel ascertains whether he has connection wit central. It he has such connection he hears the clicks in the receiver upon operation of the corresponding break wheel 50. If the line, however, is busy elsewhere and the cur- -rent, as before described, is not sufficient to have actuated the solenoid upon opening oi the box, the telephonie apparatus, therefore, remains short-circuited and Virresponsive.

The solenoid switch 20 may, therefore, beV

called a lock-out'switch or relay.

Another vey important feature of my invention, besides the lock-out feature just described, is the provision for at all times maintaining the. main line in perfect condition for transmitting calls from :lire alarm stations,

` .the fire alarm service the-most important in such systems. If, therefore, conversation were being carried on at-one of the telephonie substations and apparatus were o id switch, the core o the solenoid being can go there and lend assistance. He can ascertain the location of the actuated re. alarm boi: b listening in the receiver or by listening to t e clicks roduced by the solen- 'attracted at each closure of the line at the actuated fire alarm a paratus.

Ocers at any other tele hone su stations along the same line' will a upon opening the box, notiiei that an alarm of fire lisbeing sent in, and by listening in the receiver or to the solenoid switch they also can ascertain Where the fire is and go there if necessary. This listening to the fire alarm signal at more than one substation on a line is rendered possible because the 27 of the solenoid switches are of.

ver low resistance and their s erial inclusion line upon closure of the line at the call-A ings.

ing re alarm station will not reduce tbs current flow perceptibly, and the line, ''ieifefore, even though substation boxes wereopened and the receivers off the hooks, will be practically at its normal strength and thus in no way interfere with the most efficient transmission of the fire alarm signals.

if it were not for the low resistance winding 46, the current flow throu h the main circuit would be materially wea cned owing to the comparatively high resistance of the telehonic apparatus which would. be tele honically included serially the line. eing bridged, however, by the comparatively low resistance-winding 46, the resistance in the main line is suiiicientl upon actuation of fire affirm apparatus auflicient direct current will flow to eiciently actuate, the proper alarm apparatus. The

winding 46, however, has high impedance and the telephonie currents will all flow through -the telephonie apparatus. The

windin 46 is in circuit in the main line only at the e ,f of a fire alarm signal, bein shunted om circ'uit by the contacts 29 an reduced, kso that,`

30 upon dener ization of the solenoid 20- when the line is t broken at the fire alarm station, and thereafter the line will have onl the ve vlow resistance of the solenoid win rovision may also be made for repeating the signals from the central exchange p and repeating means such as an ordin repeating relay 64 may be included seri y'in the main line at the central exchange and the circuits 65 controlled by thisre'iay may elsewhere.

The transmitter and receiver at the substations are relatively connected as shown, the transmitter being included serially in circuit between the receiver coils 66 and 67.

I thus prfvide avery simple and eicient combination system in which fire alarm si nals and telephonie and telegraphic signa may be transmitted over a common line, the

106 4lead to sub-central or precinct stations, or

lire alarm, telephonie and telegraphic signals being analyze at the central exchange and received by distinctive receiving apparatus. The line, however, is et all times in perfect condition for receiving the more important iis iire alarm signals, the telephonie and telegraphic apparatus when such fire alarm systems are from circuit. At the same time, however the fire alarm signal can be .heard and interpreted at any of the telephonie substations. During the use of the sation from one substation, all other telephonic and telf-.graphic substations are locked against use. Police or other officer may communicate to the central attendant the number of his ke the number of the station from and hold telephonie conversa-- which'he ca tion, the communication o the number of the key being given automatically the .me for telephonie conver.
